Many water industries around the world continually contend with water quality problems caused by build-up of sediments and slimes in pipelines. These problems can ultimately lead to regular customer complaints and decreased hydraulic efficiency. Mains cleaning programs are now common practice in the water industry to improve or maintain drinking water quality to meet water quality guidelines, customer expectations as well as business plan and asset management targets.

Treatment plant malfunctions allowing turbidity and microbiological break through, burst mains replacement works, open service basins, seasonal flow/pressure variations, deteriorating old mains, irregular tank cleaning programmes and poor mains system designs all contribute to sediment build-up, water discolouration and microbiological regrowth within mains supply systems.

Chemicals will not remove accumulated slime, sludge, mussel shell, weed growth, metal nodules or scale encrustation. If hazards such as these are left unchecked it could produce readings outside water quality guidelines and lead to problems that chemicals cannot rectify. The pipeline should be physically cleaned, if for no other reason than to allow the active properties of the chemicals to work properly and by doing so, reduce the amount of chemicals used. Refurbishing reticulation water systems will solve dirty water complaints and effectively remove all loose and most bacteriological accumulated slime, sludge, manganese and general encrustation. It will improve flow rates, reduce chemical usage and can eliminate costly pipeline replacement.

The correct cleaning of large trunk mains requires sound planning and expertise in managing the operation, to ensure that no dirty water is reticulated through already cleaned pipes and minimising water disruptions to the consumers.

Clearflow Australia utilises two distinct forms of technology to clean water mains

The choice is dependent upon the circumstances.

Both methods have obvious advantages: Air Scouring in smaller diameter reticulation systems, and Pigging when it comes to larger delivery or trunk mains and even the older cast iron reticulation mains.

Both are proven methods of eliminating dirty water and unpleasant odour from the reticulation system. These two methods are designed to remove any foreign matter or growth that builds up in the pipeline and to return the internal bore to a clean and operable condition.

The result is cleaner pipes, cleaner water and satisfied customers.

Samples of water analysis reports are available on request.

Air Scouring

Air Scouring involves the injection of filtered compressed air into the water mains. Air Scouring effectively cleans reticulation mains using less water and in less time than other methods. The latest equipment used, all environmental guidelines and council policies are followed, and our crew is available 24 hours which means work may be conducted any time, night or day, to minimise disruption.

Pigging (Swabbing)

Pigging (Swabbing) is the insertion of bullet shaped poly pigs or swabs into the pipeline system. Our environmental policy can be followed in exactly the same sequence regarding the methods of discharging the water. We offer 24 hour mobilisation of crews and services for emergency Swabbing of water mains in residential and country areas.

All our services programmes are available individually or collectively as part of a Multiple Service Package.
